In addition to wireless Internet, there are wireless keyboards, printers, and mice.

It’s possible to set up a wireless network in your own home without too much
trouble, and in fact – if you live in an older existing home in which the wiring is
already installed – wireless may be your only practical choice, should you want to

network all the computers in your home.

The advantages of a wireless network include convenience and mobility; if you have
a laptop equipped with a wireless card for example, you can pretty much work

anyplace you like. It also allows you to expand your network quite easily without

having to run additional cables all over the place.

Wireless technology does cost a bit more; you’ll have to update your cable or

Ethernet modem to a wireless one, and install special cards in all your computers.

Many say this extra cost is offset by the additional productivity that seems to occur
as the result of not having to deal with extra chords.

There are however distinct disadvantages of a wireless network. Like all devices

that rely on radio frequency transmission, wireless networks are subject to
interference. If you have ever attempted to listen to a radio program while

someone is running electric trains or using power tools nearby, you know what this
is about. Additionally, there are security issues.

Wireless networks tend to use more power than their wired counterparts, and this

extra power makes it easier for unwanted third parties to intercept data. There are
encryption technologies available especially for wireless networks, but many of

these seem to have weaknesses that are easily exploited by determined hackers –
some of whom make a career out of identifying and hacking into wireless networks.

Some additional information on wireless security is available in an online article
